LTC2360/LTC2361/LTC2362
100ksps/250ksps/500ksps,
12-Bit Serial ADCs in TSOT-23
FEATURES
DESCRIPTION
The LTC®2360/LTC2361/LTC2362 are 100ksps/250ksps/
500ksps, 12-bit, sampling A/D converters that draw only
0.5mA, 0.75mA and 1.1mA, respectively, from a single
3V supply. The supply current drops at lower sampling
rates because these devices automatically power down
after conversions. The full-scale input of the LTC2360/
